Noise and temperature compensation for Graphene-ISFET micro-sensor

This work presents a new conditioning circuit for a CMOS compatible GrISFET micro-sensor, which carries out a temperature-compensation and noise reduction using a compact analog-circuit. The circuit is designed for a generic GrISFET micro-sensor, which was modelled in TopSPICE, using the AMS 0.35 μM CMOS process. The presented read-out circuit and the GrISFET sensor work under same condition. The proposed circuit shows a good immunity against noise and temperature variation.
